List, Upper Montclair, N.J., assignors to G & H Mechanical Laboratory,Inc., a corporation of New Jersey Filed Feb. 9, 1965, Ser. No. 431,25313 Claims. (Cl. 12032) This invention pertains to copyholders having apaper support. More particularly this invention pertains to copyholdersof the portable type having selectable advancing mechanism.

Even more particularly this invention pertains to portable copyholdershaving a scroll-type paper retainer, a one-way clutch mechanism drivinga paper advancing means in response to a lever actuation and anadjustable sight guide and paper support.

Even more particularly this invention relates to a portable copyholderhaving easy settable means for varying the length of incrementalmovement of a paper advancing mechanism and means for jogging theadvance mechanism to advance the same paper copy a relatively smallproportion of the incremental movement of the copy.

Copyholders of conventional construction have provided mechanism thathas been subject to the slightest variation in the manufacture offeeding wheels and other commercial tolerances required in themanufacture of the machine. These copyholders have been satisfactory inthat line adjustments of some difliculty have often been experienced,this annoyance and loss of time by the copyist has resulted in thereduction ofuse of the copyholders.

It is an object of this invention to provide a copyholder of a light,portable type, the copyholder providing a scroll-type paper retainer, aone-way clutch mechanism driving a pair of rollers in response to alever actuation, the lever actuation having an easy settable means ofproducing incremental movement in equal multiples, as for examplethirds, which movement may correspond to the single, double and triplespacing provided by a typewriter, the one-way clutch mechanism alsoproviding a means for jogging the advance mechanism to advance the papercopy a fraction of a standard incremental movement and by this means tobring the line of copy into a desired relationship to a sight guide.

It is a further object of this invention to provide a copyholder of highreliability and economical of manufacture, said copyholder having anadjustable paper support, an adjustable sight guide and means for easymounting and retaining of an enlarging unit.

In the attainment of these and other objects that will become apparentin the following detailed description, We provide a copyholder having ahousing providing a support for a hinged base and lever carrying apivotmounted scroll-type paper holder, the paper holder beingspring-biased to urge the paper being dispensed from the holder againsta pair of spaced rollers. The lever providing means to move the holderaway from the rollers andthe pivot mount providing a simple andeffective means for self-alignment of the scroll-type paper holderagainst the rollers. These rollers are carried by a shaft rotatablydriven by a one-way clutch mechanism moved by a lever and link toproduce an incremental movement which may be predetermined by an easilyseltable lever and stop mechanism. A paper support comprising a pair ofadjustable arms is pivotally attached to the paper holder. A sight guidehaving guide continuation bars is provided to define a line-of-sight orreference. guide and to support a removable magnification memLer.

The most important features of the present invention have been outlinedrather broadly in order that the detailed description thereof whichfollows may be appreciated. There are, of course, additional features ofthe invention which will be described hereafter and which will also formthe subject of claims appended hereto. Those persons skilled in the artwill appreciate that the conception on which the present disclosure isbased may readily be utilized as the basis for designing otherstructures for carrying out the several purposes of this invention. Itis important, therefore, that the claims be regarded as including suchequivalent constructions as do not depart from the concept and scope ofthis invention.

Extending outwardly from the front face and through appropriatelycut openings in this face is in advance control or limiting lever 26, anadvance lever 28 and a spring release lever 30.

Carried by release lever 30 is paper scroll 32 which, as best shown inFIGS. 1-4, is generally a steel tube with both ends open. This tube asreduced to practice is about three and one-half inches in diameter andis about four and one-eighth inches long. This tube is furtherlongitudinally split with a lip portion 34 being of a straight extentand on a tangent with the tube portion and extending at generally rightangles to a radius line from the theoretical center of the tube. As seenin FIG. 2 and at about seventy or eighty degress clockwise from the endof lip 34 there is a stud 36 fixedly attached to the scroll 32. Lever 30as reduced to practice and seen in FIGS. 2 and 4 is formed with a longerfinger grasping leg 37, and oppositely disposed and parallel shortsupporting leg 38 and a transverse beam 39 connecting the legs 37 and38. Intermediate the legs and extending forwardly as a part of the beamare brackets 40a and 40b with .aligned hole 41 through both brackets.Stud 36 is inserted in hole 41 and is then riveted in place so thatscroll 32 is pivotally carried by the lever 30. By precisely spacingbrackets 40a and 40b and controlling the planing of the stud end of stud36, the brackets can be caused to act as biased beams so that scroll 32can be turned around the axis of the stud but will be frictionallyretained from freely swinging around the stud axis. The lever 30 ispivotally attached to sides 23 and 24 by means of rivets 42.

As seen in FIGS. 2, 3 and 8 there is mounted a short distance below theupper edge of housing 20 a roller shaft assembly 44. This assembly 44 isrotatably mounted in bearings 45 in the sides 23 and 24. A shaft 46which may have reduced end portions 47 for mounting in the bearings 45also has fixedly attached and adjacent each end portion 47 a roller 49which preferably has a round rubber tire 50 mounted thereon.Intermediate the rollers 49 is a clutch 52 which is a one-way clutch tobe more fully described below. As seen in FIG. 2 a spring 54 extendsfrom finger leg 37 to a spring tab 55 attached to or otherwise made apart of right side 24. This spring 54 urges lever 30 to move clockwisearound rivets 42 and to move scroll 32 into contact with rubber tires 50of rollers 49. As scroll 32. is pivotally mounted, as described above,the scroll 32 will align itself to contact the tires 50 on both rollers49.

clockwise rotate without similarly rotating the shaft.

The clutch 52 mounted on shaft 46 is a spring type torsion clutch whichas installed and used is adapted to operate the shaft in only onedirection. As reduced to practice, the clutch includes a housing 58which is rotatably mounted on shaft 46. A shouldered bore 59 is adaptedto slidably and to snugly retain a closely wound spring 60 which, asshown and reduced to practice, is wound left-handed. The spring 60 shownis tightly wound and is intended to lightly grip the shaft 46 with thespring wound about a one to three thousandths of an inch lesser insidediameter than the diameter of the shaft 46. The bore 59 in the housing58 and as reduced to practice is approximately five thousandths of aninch larger than the outside diameter of the mounted spring and thelength of bore 59 is such that when mounted, spring 60 is retained witheach coil contacting each adjacent coil.

It is to be noted that spring 69 is formed with an outwardly directedtab end 62 which engages and is rotationally retained by a groove 64formed in housing 58. To retain the spring 60 in the bore 59, there isprovided a spacer washer 66 retained in the housing by a snap-ring 68mounted in a snap-ring groove 69 formed in the enlarged end of thehousing. The housing 58 is preferably made with two flanged ends whichprovide a recess for the end of a drive link 70. Aligned pin holes 72are drilled in the flanges, and a connecting pin '73 is inserted in eachof the holes 72 while at the same time passing pivotally through the endof link 70.

In use, as to be more fully described hereafter, the drive link 70 iscaused by other mechanism to move downwardly. This downward movement oflink 70 in turn causes the housing 58 to move clockwise as shown by thearrows, the tab 62 of the spring 60.is also moved clockwise, and thespring 60 already snugly around shaft 46 is caused to be more tightlywound around the shaft. This additional tightening of the spring issufficient for it to grip the shaft 46 and to clockwise rotate thisshaft an amount substantially equal to the rotational movement of thehousing 58. After the clockwise rotation has been completed, the housing58 is moved back to its original position by an upward movement of drivelink 70 to its normal up position. This movement of link 70 is by meansto be described below. As the housing is moved counterclockwise, the tab72 of the spring is also moved therewith causing the spring to move andslightly unwind. This slight unwinding of the spring as the housing ismoved in the counter-clockwise direction releases the grip of the springon the shaft 46 and allows the housing to counter- It is to be notedthat the shaft is maintained under a slight frictional load so as toprevent any unwanted shaft rotation. In the present instance it ispreferred to provide this low friction by applying a light load againstthe shoulders of the reduced end portions 47 of the shaft 46.

In FIG. 9A is shown an alternate clutch body mechanism which in manyrespects is the same as the clutch 52 of FIGS. 9 and 10. This alternateclutch is a modification of the above described clutch and is simplifiedin construction to provide certain manufacturing economies. Thismodification renders this clutch less foolproof than the clutch of FIGS.9 and 10, however the backlash that may sometimes occur is of such asmall percentage that in most applications of this copyholder the amountof developed backlash can be ignored. This alternate clutch designated152 includes a housing 158 which may be identical to housing 58 exceptthat a less expensive bore is provided, this bore having no undercutsmay be molded in a housing of plastic or a metal die casting. Bore 159may have a chamfered inlet and then a constant diameter portion of lessextent than bore 59. This bore 159 snugly retains a closely wound spring160 which as shown is wound lefthanded and has about half as many turnsas spring 60. 7 Spring 160 is of a lesser length than bore 159. A shorttransition may be formed from bore 159 to a reduced rear bore 161 whichis a rotating fit upon shaft 46. This bore 161 is of sufficient lengthto provide a bearing surface which will reduce wobble of the housing onthe rotating shaft. A tab 162 on spring 160 is engagable in a groove 164formed in the flange of housing 158. This tab 162 is attached orretained in groove 164 by glue, solder, or by closing the groove 164 bydeformation of the flange. By one of these means, the spring 160 ismaintained within bore 159. As spring 160 is not longitudinally retainedwithin the bore 159, the spring may flex a slight amount before grippingthe shaft, thus creating a small amount of backlash. The maintenance ofa spring and bore relationship in clutch 152 which is about the same asin cluch 52 provides for a backlash which is usually less than one ortwo degrees of rotation.

Referring now to FIGS. 3, 5 and 7, there is provided an advance leverassembly 28 which includes a right and left pivot arm 74 and 75, pivotpins 76 and 77 each extending from the end portions of an arm 74 or 75.Intermediate the arms and as formed from the same sheet of metal is thefinger plate 78. A portion of this plate 78 extends through an openingin the front 22 of the housing 20. Extending upwardly from a portion ofthis plate is a pair of link brackets 80 and 81 having holes therein tocarry a lower connecting link pin 82. As shown in FIG. 3 the lower endof link 70 is disposed between brackets 80 and 81 and by means of pin 82is pivotally attached to this advance lever assembly 28. A tensionspring 84 extending from the inner edge of finger plate 78 to the shaft46 provides a bias to move and maintain the lever assembly 28 in anupward position. It is to be noted that the pivot pins 76 and 77 arecarried by brackets 85 formed from the sides of the housing.

Upward movement of the advance lever assembly is regulated by theadvance control lever 26 which as seen in FIGS. -3, 6 and 7 ispreferably a single sheet metal stamping having a :beam portion '88 witha pivot hole 89 formed on the inner end thereof. Adjacent this pivothole there is in the preferred instance an embossed dimple portion 90for a purpose to be described below. Approximately one third of the wayfrom the outer end of beam portion 88 there is provided a stop arm 92having its outer end bent so as to provide a stop surface for engagingthe finger plate 78 of the advance lever 28. Out wardly from arm 92 andadapted to lie in the plane of front plate 22 there is embossed in thebeam 88 a longitudinal protrusion 94. As assembled for use the controllever 26 is mounted on pivot pin 77 of advance lever 28. The innersurface of the beam end is slidably engaged and retained by bracket 85,and the dimple 90 engages the inner surface of the housing side 23. Thebeam 88 then extends upwardly and outwardly to and through anappropriate cutout 96 formed in cover 22. The beam 88 is bowed or bentso that when mounted on pin 77 as shown in FIG. 7 the dimple 90 willengage the inner surface of the housing side 23 and the outer portion ofthe beam carrying protrusion 94 will engage the inner longitudinalsurface of the cutout 96, FIG. 11. It is to be further noted that theinner longitudinal surface of cutout 96 has a series of semicircularserrations 97 formed therein. In the present instance these serrationstotal three and are indicated by numerical indici-a applied to thesurface of the front face 22. In use the serrations 97 are so spaced andnumbered that when the lever 26 is placed with protrusion 94 atserration 1 as seen in FIG. 11, the stop arm 92 will engage plate 78 soas to limit the up-and-down travel of advance lever 28. This limit oftravel is translated into rotational movement of shaft 46 so as tocorrespond with a total circumferential equivalent linear movement oftire 50 equal to the space of one line of typewritten copy. Accordingly,when the lever 26 is placed with protrusion 94 at serration 2 the stoparm 92 will move upwardly increasing the upper limit of travel ofadvance lever 28.

The up-and-down movement of lever 28 is now intended to be translatedinto a circumferential linear movement of tire 50 equal to two lines oftypewritten copy. Further, when the lever 26 is moved to placeprotrusion 94 at serration 3, the stop arm 92 will have been movedadditional-1y upward to permit the movement of advance lever 28 totranslate the circumferential linear movement of tire 50 into a movementequal to three lines of typewritten copy.

Attention'is now directed to the preferred sight guide apparatus andparticularly to the apparatus as shown in FIGS. 1-3 and 12-16. It is tobe noted that there is no top for the housing 20 as formed in the"blanking and bending of the front face 22 and sides 23 and 24, hence tofurnish a top or cover for the housing there is provided a channel guide98. This channel guide serves not only as a cover for the open top ofthe housing but also provides an alignment or sight guide for theconvenience of the operator of the apparatus. As illustrated, thischannel giude is intended to be snapped in place on the top of thehousing 20. A preferred arrangement utilizes a plurality of holes 100which are drilled or punched in the front face and which are locatednear the upper edge of the face 22. In the front leg 102 of guide 98there are formed dimpled portions 103 which are of such a size andspacing as to mate and seat in the holes 100 in the front face 22 whilethe front leg 102 lies thereon.

An intermediate portion 104 of guide 98 is formed so.

as to be substantially at right angles to leg 102. This portion 104 isadapted to lie on the upper ends of sides 23 and 24. Portion 104terminates in a channel 106 which in the present instance is athree-sided bent continuation of the sheet metal forming the guide 98.Engaging tabs 108 (FIGS. 2 and. 14) are also formed from this sheetmetal. These ta'bs are of short extent and are in the plane of the lowerwall of the channel 106. As reduced to practice, there are two tabs 108which are spaced so as to engage the sides 23 and 24. As seen in FIGS. 2and 3, the upper inner corner of the side 24 is cut to receive thischannel 106 and a notch 109 is also formed to accept and retain tab 108.Side 23 is cut in a manner similar to side 24 so as to receive theportion of channel 106 and the tab 108 corresponding to that side. Tomount guide 98 to the housing 20, the tabs 108 are slid into theappropriately formed notches 109 in sides 23 and 24, the forward wall ofthe channel 106 is brought into engagement with the sides 23 and 24, andfront leg 102 is brought over and lightly sprung outwardly while beingpushed down the outer surface of front face 22 until dimpled portions103 engage and are seated in holes 100, by which means the guide 98 isbrought downwardly into snug engagement with the housing 20. In thismanner there is provided a biased retention of the removably mountedguide 98 to the housing 20.

The channel guide 98 provides with its portion 104 a straight surfacededge which provides a line-of-sight or a reference guide or point. Theextended. channel 106 which is a continuation of portion 104 is also aretaining guide for the retention of guide continuation bars 110 whichare particularly seen in FIGS. 1, 14, 15 and 16.

' In the present instance rectangular aluminum bar stock is cut to apredetermined length. An end portion 112 is bent with a ninety degreetwist and a ninety degree bend to a main beam portion 114 comprising theremainder of the bar 110. Disposed adjacent the unbent end of beamportion 114 there is formed an engaging means. In the preferredembodiment as seen in FIGS. 14-16, this engaging means is provided inthe form of a tongue 116 which is lanced or pushed out from the mainbeam 114. This tongue 116 has the spring bias and deformingcharacteristics of the metal of the beam, and in the forming of thetongue it is bent so that the unattached or free end is caused toproject beyond the face of the beam portion 114. The tongue is formedwith its attached end dis posed adjacent to the unbent end of the mainbeam 114.

The channel 106 (FIGS. 14-16) is formed with end guides 118 whichprovide an opening of such size as to slidably retain the rectangularcross-sectional construction of the beam 114. It is to be noted in FIG.16 that, as illustrated, the left end guide 118 is formed so that theopening for the left beam 114 is adjacent the rear wall of channel 106.The right end guide 118 is formed so that the opening for the right beam114 is adjacent the forward wall of the channel 106. As seen in FIG. 15,the guide bar 110 is easily mounted in the channel 106; the end of themain beam 114 is inserted in the end opening in the channel 106, and the:beam is pushed into the channel. As tongue 116 approaches the end guide118, it is deflected by the guide into the plane of the beam. Afterpassing the guide and moving into the channel, the bias of the tonguecauses it to once again spring into the bent position shown in FIG. 15.

The right guide bar 110 is similarly mounted in the channel 106. Afterboth right and left guide bars 110 are mounted in the channel, they arepushed further inwardly until they meet, and then in the manner shown inFIG. 16 they are manipulated so that the inner ends pass each other, thetongues 116 of each bar deflecting to allow the other to pass. When thetongues have passed each other in the manner shown in FIG. "16, thetongues provide limiting means for the outward movement of or Withdrawalof the guide bars 110. As reduced to practice the approximate length ofthe channel is twelve and three-quarters inches, while the main beam 114of each guide continuation bar 110 is about twelve and one-half inches.The free end of the tongue 116 is twelve inches from the bent endportion 112, which arrangement permits the bars 110 to be pushed intothe channel 106 until the bent end portions 112 engage the end guides118. When fully inserted or in the closed. position the end portions 112will then be about twelve and one-half inches apart. When fully extendedand with the ends of the tongues 116 engaging each other, the endportions 112 of the guide :bars 110 will be twenty-four inches apart. Bymaking the internal width of the channel 106 of limited extent so as toaccommodate the two thicknesses of beams 114 and to further accommodateless than the free projection of the combined tongues 116, the positiveengagement of the tongues 116 to each other is assured. In theembodiment shown and reduced to practice, the internal width of thechannel is one hundred sixty thousandths of an inch; the thickness ofthe beam 114 is seventy thousandths of an inch, while the projection ofeach tongue is fifteen thousandths of an inch. As thus proportioned thebars 110 can be freely moved longitudinally in the channel 106 withoutundue engagement of a tongue 116 with an oppositely disposed main beam114. A desirable light frictional engagement of the bars 110 to eachother and to the walls of the channel 106 is provided by the lack ofaccurate straightness in the main beam 114 which is achieved byutilizing only commercial- 1y straight extended bars and the inadvertentbending of the beam 114 while the beam is grasped in dies as tongue 116is being formed. The resulting beam 114 has a slight how or deviationfrom a true plane, said deviation providing all the light frictionnecessary to maintain the guide bars 110 in the adjusted position.

In FIGS. 1-3, 12 and 13 is shown a preferred paper support means. Saidpaper support means include a plurality of movable arms which in thepresent instance are ,two and which may be moved from a generallyhorizontal storage or repose position to a generally vertical operatingor paper-supporting position. there are cut and bent two lug supports120, each having therein a. hole for the insertion and retention of arivet 122. An arm 124 is, in the present embodiment, formed with a holein one end thereof. This hole is additionally formed at the apex of aconically formed portion 125 which is further distinguished by havingthis conical por- -tion radially cut at a plurality of points 126. Thisresult- For paper scroll 32 ing resilient washer construction,-similarto a Belleville type washer, provides a shake-free, resilient, rotatablemounting of the arm 124 to the lug support when the rivet 122 is mountedin the respective holes and the small end of the rivet is preciselyheaded or turned over.

It is to be noted in FIGS. 1, 2 and 3 that th rear edge of sides 23 and24 are formed with an arcuate shape 128 which is so disposed that whentire 50 of the roller 49 engages the paper scroll 32 the arcuate shape128 lies forwardly of the exterior of the paper scroll and by an amountgreater than the thickness of heavy paper.

It is to be further noted in FIGS. 1, 2 and 3 that an accessoryenlarging or magnifying unit 130 is readily mountable on th channelguide assembly 98. As shown, the magnifying unit 130 has a plano-convexcross section and is preferably made of acrylic plastic. This unit 130is cut or formed of a selected length, and in each of the ends there areformed grooves parallel to the plano surface, the grooves being of adepth and width to accept and retain the end portions 112 of guide bars110.

An alternate embodiment of sight guide apparatus is shown in FIGS. 1724in which a channel guid is similar in form and use to the guide 98 andprovides a cover for a slightly modified housing designated 20a. Thisguide 150 similarly snaps in place on a housing 20a which is the same ashousing 20, but instead of having the notches 109 shaped as seen inFIGS. 2 and 3, has notches 152 which have sloped sides and a hookportion 153 adapted to engage the underside 154 of tab 155 formed inguide 150. In the front leg 156 of guid 150 there are formed dimpledportions 158 which are of such a size and spacing as to mate in holes100 in the front face 22 of housing 20a while the front leg 156 liesthereon.

An intermediate portion 160 of guide 150 is formed so as to besubstantially at right angles to leg 156. This portion is adapted to lieon the upper ends of sides 23 and 24. Portion 160 terminates in achannel 162 which, as shown, is a four-sided bent continuation of thesheet metal forming the guide 150. Engaging tabs 155 (FIG. 19) are alsoformed from the sheet metal. These tabs are of short extent and arepushed downwardly from the plane of the lower wall of the channel 162and intermediate portion 160. As reduced to practice, there are two tabs155 which are spaced so as to engage the hook portions 153 of sides 23and 24. To mount guide 150 on the housing 20a, the tabs 155 are slidinto the notch 152, the underside 154 of tab 155 engaging the hook 1portion 153 of the sides. The front leg 156 is brought over and lightlysprung outwardly while being pushed down the outer surface of front face22 until dimpled portions 158 engage and are seated in holes 100, asdescribed in conjunction with guide 98 above.

In channel 162 there are disposed two guide continuation bars asparticularly seen in FIGS. 21-24. In this embodiment a rectangular steelbar is cut and bent as in the manner of bar 110, however the tongue 116of bar 110 is replaced with a dimple 172 disposed in th flat portion 174and formed by embossing dies. As particularly seen in the sectional viewFIG. 22, the dimple 172 is essentially extruded or displaced from theplane of the flat portion 174 and forms a smooth rounded protuberanceextending therefrom. Extending at right angles to portion 174 is endportion 112a which is identical to end portion 112.

In opposite walls of channel 162 there are formed outwardly extendinggroove portions 176a and 176b, each groove of a determined length andterminating substantially before the end of the channel 162.

The channel 162 is formed with appropriate end openings to slidablyretain the rectangular cross-sectional construction of the beam portion174. To assemble th two bars 170 within the channel 162, the bars 170are arranged with the dimpled portions 172 dispose-d outwardly in themanner as seen in FIGS. 23 and 24. The channel 162 may be sprung open anamount sufiicient to accept these bars, or the bars may be placed in thechannel immediately prior to the forming of the last closing bend andthe channel then bent to final form. The bars 170 when thus assembledare restrained in longitudinal movement by the extent of the grooveportions 176a or 1761;, the length of flat portion 174, the location ofdimple 172 therein, and the extent of groove 176 being arranged byconstruction to provide th amount of longitudinal travel desired. Otherdetails of this sight guide assembly are similar to the sight guideapparatus of FIGS. 1-3 and 12-16 described above. The use and operationof this assembly will be described below.

Use and operation To use the copholder shown and described aboverequires three very simple manipulations. The operator grasps in on handthe piece of paper or similar material which is to be copied; meanwhilewith the other hand the operator grasps spring release lever 36 andmoves the lever upwardly to the position shown in the phantom outline inFIG. 2. As lever 30 is moved, so also is paper scroll 32 moved to theposition indicated by the phanton outline. Placing the paper forwardlyof arms 124 and behind guide bars 118 or 170 (with or without magnifyingunit 130 therein) the paper is slid downwardly between scroll 32 androllers 4-2. As the paper is continued to be fed downwardly the forwardedge of the paper will engage lip portion 34 and will be guided into theinner portion of the scroll 32, and following the direction of thearrows of FIG. 2 the paper will be rolled upon itself into a scroll.

After the paper has been advanced into the scroll 32 an amountsufficient for the top line of copy to just be visible above theintermediate portion 104, the lever 30 is released so that spring 54will bring the lever 30 and scroll 32 to the position shown in solidlines in FIG. 2. The paper carrying the copy has one side thereofretained in sliding relationship with the smooth outer surface of scroll32 and with the other side of the paper engaging the rubber tires 50 ofrollers 49.

Referring now to FIGS. 3 and 5, the lever 26 is placed so thatprotrusion 94 is engaged in that serration 97 which is numbered tocorrespond with the spacing of the copy. As for example, if the copy isdoubled spaced, the protrusion 94 is adjusted to seat in the middleserration which is numbered two. To advance the paper being copied, theadvance lever 28 is moved downwardly until stopped by the inward turnedlower lip 131 of front face 22. This lower lip may have a rubber bumper132 mounted thereon so as to reduce the noise of contact of lever 28against lip 131. As described above, drive link 70 is moved downwardlyan amount as controlled in the upper extent by the stop arm 92 and inthe lower extent by lower lip 131 or bumper 132. This downward movementcauses clutch 52 to engage and rotate shaft 46 in a clockwise directionand in an amount as controlled by the upper and lower limited movementof advance lever 28. As shaft 46 revolves, the rubber tire 50'frictionally engages and drives the copy paper upwardly and draws saidpaper from the paper scroll 32 in the direction of the arrows as seen inFIG. 3.

It is to be noted that a light tapping of the finger on the advancelever 28 will cause small downward movements of the drive link 70resulting in short rotational movements of the shaft 46 and rubber tire50. This permits the paper to be joggedupwardly when desired to correctfor irregular spaced copy or to otherwise move the paper upwardly forirregular distances.

The convenience of the user is accommodated in the support of theexpelled or exposed port-ion of paper copy. To suit the particular copybeing'copied, the arms 124 are pivotally swung to any desired positionextending from horizontal to the vertical position shown in FIG. 1.

The sight guide formed from channel 106 and'the guide continuation bars110 are adjustable by the user from an inner limit as controlled by thelength of channel 106 and to an outer limit as controlled by theengagement of each tongue 116 with each other. The alternate embodimentin which is used the channel 162 and bars 170 is adjustable within thelimits imposed by dimples 172 residing and moving in enclosed grooveportion 176, or may be limited in its inward movement by the engagementof the twist in the bar 170 with the outer end of the channel 162.

The magnifying unit is mounted for use by adjusting guide bars 110 or sothat end portions 112 engage each end and longitudinally retain unit130. End slots in unit 130 engage end portions 112 or 112a which areseated therein to provide alignment and vertical support While channel106 or 162 provides the bottom support for the removable magnifyingunit.

The copyholder shown and described above is of light weight and isreadily portable for movement to any desired location, hence in theforegoing description the terms right, left, up, down, front, rear andsimilar terms are applicable to the apparatus as described inconjunction with the accompanying drawing, and it is to be noted thatsuch terms are merely for the purpose of description and do notnecessarily apply to a position in which the apparatus may beconstructed or used.
